armrests

I have a friend who had some FJ45 (?) parts he no longer needed and I'm looking to pass them on to someone who needs them. Would rather sell it all than in pieces but will sell individually if it makes sense.

I recently removed the third row seats of my new-to-me 200, which was a horror story for a different time. But in the process I noticed these funny things stuck in what would be the third row armrests. Any idea what they may be? They're on both sides... Thanks, Ryan
